[AArch64] Add SME implementation of ARGBToUVRow and similar

Browse Source 
Mostly just a straightforward copy of the existing SVE2 code ported to
Streaming-SVE. Introduce new "any" kernels for non-multiple of two
cases, matching what we already do for SVE2.

The existing SVE2 code makes use of the Neon MOVI instruction that is
not supported in Streaming-SVE, so adjust the code to use FMOV instead
which has the same performance characteristics.
